Sunrise sunset - benanderson_475 - 05.11.2019 Is a lan connection required to use scheduled sunrise/sunset? And dose this function run if there is no internet connection? RE: Sunrise sunset - admin - 05.11.2019 It's calculated internally based on current date and configured coordinates. Internet connection is not required. RE: Sunrise sunset - Erwin van der Zwart - 05.11.2019 Hi, I don’t fully agree with that, without internet you don’t have NTP so you risk a wrong time after power outage, I would add a KNX time DCF77 and a script to keep the controller on time...

RE: Sunrise sunset - Erwin van der Zwart - 05.11.2019 Hi, Yes, you can add a knx time and date object to the visu and a TAG to it and add this as a event based script to it that is triggered by the TAG: Code: if event.sender == 'us' then -- Only execute when action comes from visu To keep the objects in the visu up to date with the system time you can add this script as resident at 60 seconds: Code: -- get current data as table Erwin RE: Sunrise sunset - admin - 06.11.2019 You can also use USB-GPS if antenna can be placed somewhere where GPS reception is possible.

And altso a KNX clock with a built-in battery can be used. But these of course need a little adjusting of the time along the year. GPS is better. RE: Sunrise sunset - admin - 06.11.2019 LM has built-in real-time clock and there's a super capacitor instead of battery which will keep the clock going during a short power outage.

That was new to me. Clever! It's very rare that there is a long term outage in my area. But i know places nearby where there is power outage for several days almost every time there is a big autumn storm. Will the super capacitor last several days, or are we talking about hours? RE: Sunrise sunset - admin - 06.11.2019 Only several hours. You should install a UPS if long outages happen often.

Hi, Always a nice discussion, in my opinion you should connect a IoT device to a network that supports IoT features (: If you don't you will lose functionality.. If you use our time sender MTN677290 you can connect a DCF77 antenna and set in the parameters the daylight saving time period so you don't need to change along the year. But i agree that a USB GPS probably would be a cheaper solution. @Admin: Does it work native or do we need a script to set the time from the USB GPS fetched data? BR, Erwin RE: Sunrise sunset - admin - 06.11.2019 There's no ready-made script but NMEA protocol is fairly simple (ASCII-based). You need to read lines from serial port and split them into chunks separated by ",". Then extract time/date from field values. There are also GPS receivers with RS232. These need an extra power supply but can have longer cables compared to USB.

Hi, I will figure that out when needed, no problem, just was curious if it was native, but was expecting this answer already (: BR, Erwin RE: Sunrise sunset - lenze90 - 28.11.2019 Hello, everybody, I have seen that I can specify date, time and latitude and longitude in the settings of the logic machine. I want the outdoor lighting to turn on at sunset. What is the easiest way to query this sunset condition? Thank you very much and best regards Chris RE: Sunrise sunset - Erwin van der Zwart - 28.11.2019 Hi, The easiest way is to create a scheduler with sunset/sunrise events and attach it to your outdoor light object. BR, Erwin RE: Sunrise sunset - lenze90 - 29.11.2019 Sorry, I need a little more help. Where do I find the option to choose Sunset? Where can I do that? I can't find anything. Do I do this by code? RE: Sunrise sunset - admin - 29.11.2019 Which firmware version are you using?
